Now rclerring to the parts constituting rhc dcY'u-c cmhodying myinvention, 'the same, as illustrated in tho Stlltl drawings, areconstructed as follows:

1 indicates a gcar pinion mounted on the platcn ahat't olilRitle of theand plate B of the carriage frame and arrhnged either to turn with or toturn on said platen shaft hv illtttllH of a clutch tlcvicc operatedthrough t-hc ondwisc niovcuicnt. oi. the pinion on the shaft. in theparticular construction shown, said pinion is inount'cd on tho slccre l:of the turning knob in such manncr as to have both cndnisc and rotatircinovcinont thoroon. Said pinion in providcrl on its inncr or lci't-handtaco with a scrics of radial notches, as (:lcarl t' Fttll in Fig. T, andthe slccrc ii is proridod with a radial pin 11 adapted to cngaggc anytmt of said notchcs and to ho brought into cngagcnicnt thcrcwith ordisconatruction shown. the spring 1 has the form of a spirally coiledspring surrounding 'the'slccvo I: and attached at its outer pad to the:lattcrf 'Ihc inncr cud of said spring 'lwars against an annularoutwardh facing hcariug surfmre or sliouldcr on-sai 'pinion.

Said pinion is shown as provided with 'a tubular cxtons on or slcc-rc iwhich surrounds J indicatca a gear wheel mounted on the oa-rriagct'ranie by means of a p vot. stud JR. and which intcrnicshcs-with thepinion I.

l Thc pi ot stud 'J' is located at the rear of Ito the platen shaft andabove and at the rear of the rock-shaft G; the parts being so arrangedthat the rim of the wheel is located radially outside of the hub of thelever G. Said rim of the wheel is, moreover, connected with the pivot Jby a sin le, radial arm J so that the wheel is adapted to swing to a,desired distance without contact will the said hub g of the lever G.

evices are provided by which the 1ggar pinion I is automaticallydisengaged m the platen shaft in the forward turning movement of theplaten and is thrown into engagement with said platen shaft by thebackward turning movement of the aten, as follows: Attached to thepinion is a radial arm I which overlaps the rim of the wheel J at theouter or ri lit-hand face of the same The said gear w eel J is rovidedon t e outer or right-hand face 0 its rim with a cam pro'ection Jhaving. a beveled or inclined sur ace 7' on the side thereof .whichcomes in contact with the arm I when, in the forward turning movement ofthe platen, the pinion I turns the wheel J into position to bring thesaid cam projections J into enga ement with said arm 1 as 'seen in Fig.3. he pinion I intermeshes with the earwheel J in such manner that thearm will;coincide with the cam projection J hen in the turning movementof the pin" n the arm I is directed toward the center of said wheel J.The cam surface 7' of said cam projection J is adapted to enter behindthe arm I in such manner as to press or force said arm toward the right,and to thereby move the arm and gear pinion outwardly on the platenshaft far enough to release the gear pinion from the pin it and tothereby hold said pinion disconnected from said platen shaft. The saidcam projection J is located on the rim of the wheel J at a pointadjacent to the supporting arm I of said wheel, so that said cam proection 'will be engaged with the arm I at a time when the gear wheel Jis turned to bring the said arm J 2 in a 0sttion in which .it extendsforwardly om the pivot J, or toward the platen shaft; this being thelimit of the turnin movement of the said wheel J in the irection inwhich it is turned in the forward turning movement of the laten.Preferably the rotation of the whee J, in this direction is limited bymeans of a stop projection adapted to strike the hub g. of the lever asseen in Fig. 3. As hereinbefore stated, the 5 ring I is adapted toproduce frictiona engagement between the platen shaft and the pinion Iand i' follows that when the-:said pinion is he] in a" osltion freefromen a' ment with the 'pn' hhy the action 0 t e cam projection J onthe arm 1*, in the manner above described, if the.

platen shaft. be turned backwardly the frictional engagement between thesaid shaft and the pinion I will effect the turning of the latter withthe shaft. It follows that when the cam projection 1 is en aged withthearm I and the parts are in t e position shown in Fig. 3 backwardturnin of the platen shaft will result in the sai inion I and the arm Ithereon being turne backwardly, producing a reverse rotation of the gearwheel J and carrying the said cam projection J out of engagement withthe arm I", thus permitting the gear pinion to become ree'nga ed withthe pin It and the pinion to be t ereby locked to the platen shaft. Itfollows that soon after the beginning of he backward turning movement ofthe platen shaft, when the parts are in the position shown in Fig. 3,the pinion will be locked -to said latenshaft and will then positivelyturn t e gear wheel J It follows from the above'that the cam projectionJ and the arm I on the pinion constitute in effect a clutch.operatingdevice by which the pinion I is automatically disengaged.

from the platen shaft by the forward turning movement-of the platen andis ret ngaged with or locked to said platen shaft in any backwardturning movement of the platen. .It, will be apparent, moreover, thatthe platen "will be free to turn forward, or in the paper feedingdirection, at any time and that after the forward turning movement ofthe platen has brought the cam projection J in poition to act on the armI and 'thus disengage the pinion from the platen shaft, further forwardturning movement of the platen may continue indefinitely withouteffecting any movement of the wheel J, but,'u on any backward turningmovement of t e platen shaft, the pinion will be immediately locked tosaid shaft and such backward turning movement will be transmitted to thewheel J, which latter will turn iii a direction to carry its top portionbackwardly or toward the rear of the carriage. such backward turningmovement of the wheel J is employed to indicate or measure lhe extent towhich the platen is required In the operation of my device,

J of the wheel J is mounted on a hose-plate L which is dctuchablyserurcd lo the end frame plate B of the carriage, in order to facilitatethe attachment of the indicating device to and its removal from themachine.

In connection with the gear wheel J. arranged to be tnrncdhy its grin-edconnection with the platen in the lmrlnvurd turning movement of thelatter as described. means are provided for ndicating to the oprratorwhen the platen has been turned lmckwardly the desired extent, or, inother Words, when the backward turning movement of the distance throughwhich the platen is turned backwardly.

As shown int the base-plate L is elevated part or rib L,

be accompanying drawings,

' t which is located closely adjacent to the, inner face of the wheel Jand in which are formed a series of holes k arranged at lme space'-distances apart and adapted to receive a stop pin K located inposition for contact therewith of the arm J of the wheel J when saidarmswing s rearwardly in the backward turning movement of the platen. Saidelevated parts L of the plate L is also provided with a scale M markedto correspond with line space intervals of the platen. Said scale M maybe used in connection with the adjustable stop pin K to facilitate theplacing'of said stop pin or, if an adjustable stop he not employed, theoperator may determine the distance through which the platen ment of thearm J along;

' in Fig. 3.

is turned ba ckwardly by observing the moveor over said scale.

N indicates a 'mova le stop or catch mounted onthe gear wheel J andadapted to be moved into position for engagement with the top snrfaceofthe arm I at the time the cam )roject-ion J 3 is engaged with thesaidarm and the pinion is held in disengaged or unlocked position, as shownSaid movable stop or catch is shown as having the form of a sliding boltor bar mounted in guides on the outer face of the arm J 2 of the wheel Jand which .iS.

movable endwise or in a radial directioh'so' that its outer end maybeengaged with or;

withdrawn ;from the arm 'I. n t'he'par- 'ticular construction shown, andas s'een'in detail in Fig. 9, the sliding stop N is provided ,on -itsinner face with two notches 'n n ada ted to be engaged by a leaf springN whic is secured at one end to the inner face of the wheel J andextends through'a said 'notches n n/h- Said notches are-jmade ofii-shape so that thes ring will be readily therewith an ofthe fin r.Said spring holdh theistgpyieldingly" "are shifting or. moving gamesammasto N is advanced to io'rward position a line space mtcrvab' of 1provided with a curved i the outer face of V r I disengaged there- Ifrom when" the stop is moved endw'ise fb en a ges the topsurface -01 theemit, as sho wnfin- F-ig. e, 1

said arm and the "ear pinion 1 will be held from'turning with the platenshaftin the bm-lnrard turning movement of said shaft, through thefrictional connection of the pinion with the shaft aii'orded by thesprin 1 I, aiid the disengagement of the/arm I rom the cam projection Jin such backward turning of the platen shaft will thereby be prevented.The movable stop N, therefore, constitutes a means by which the pinionmay be held or locked out of engagement with the shaft, thereby throwingthe indicating {device entirely out of action leaving the shaft andplaten to be turned freely in either direction without producing anyoperation of said indicating device.

The purpose of the paper movement indicating device above described isto indicate to the operator the extent of backward turning movement ofthe platen required when inserting sheets on which bills or invoices areto be printed where it is desired to make out a number of bills orinvoices and to make carbon copies 6f the same on a single strip or longsheet of pa er. In a case of this kind it is dcsirableit rat the carboncopies on the record sheet should be spaced as closely together aspossible, but atv uniform distances apartor with equal spaces betweenthe several carbon copies. The line space to enable the operator toreadily insert new sheets for each separate bill or invoice in suchmanner that'the first printed 'line of each carbon copy shall be locateda desired distance of one, twoor more lin spaces from the last printedline of the precedingcopy. Assuming that the record stri and a sheet ofpaper for the original biil chinetogcther with a carbon sheet betweenthem, the first bill or invoice may be printed and carbon copy will bemade in the nsnaL manner on the record sheet. The printin r j of thebill or invoice havin v been complete the same may be removed ir'o'm'the machine by releasing the guide rollers from the platen by the leverG, or otherwise, and this will he done with-out disturbing the ositionot' the record and earbcnsheets. he platen will then belturnedbackwardly,"carrying insertion ofthe new'invoice sheet, and the wardlymust be such that whenthe new -in'- 'voieestieet is inserted thepart. ofthe new sheeton-which the first line is'to be printed 'willbe located atsuch distance from thelast line ofthe carbon copy as to leave the de-'sired s aice between the co 'i'es. ,In using first ,bill'orinvoiceltnsbeen rinted and re- ]moved from the machine, wit: out disturbingthe-record and-carbon'shee ithe p'rintin of the firsfliinvoiceWyill''aceomplishe I, .--s w EMT 4 ms.

tit)

usually when the gear pinion I is locked in its disengagedhposition bythe use of the movable sto) as shown in Fig. 3, and said stop will beshifted backwardly to free it from the arm I after the completion of thefirst invoice. The platen will then be turned hackwardly, the first partof the backward turning movement resulting in the pinion I bein rotatedwith the platen shaft, by means 0 its frictional engagement with thesame, until the arm I is disengaged from the cam projection J" when thepinion will become locked to the platen shaft. As the backward turningmovement of the platen continues, the gear wheel J will be turned untilits arm J strikes the stop pin K which is located in position to stopthe backward turning movement of the stop at the desired point, or ifthe scale M alone be relied upon, the platen will be turned backwardlyuntil the said arm reaches the desired position upon the scale. Upon thecompletion of the backward turning movement of the platen, the newinvoice sheet will be inserted and the platen will be turned in aforward direction to feed the invoice sheet, together with the recordand carbon-sheets, into position for printing the first line upon thenew invoice sheet. As

the platen is turned forwardly the gear pinion I will turn with theplaten shaft until the invoice sheet is brought into position for theprinting of thefirstdine thereon, at which. time the cam projection Jwill come into contact with the arm I and the pinion l' will be thrownout of engagement with the platen shaft. The printing of the secondinvoice sheet may tien he proceeded wlth without any movement beinggiven to the gear wheel J. As soon, however, as the priutedinvoice sheethas been removed, and backward turning movement given to the platen. thegear pinion will be againithrown into engagement with the platen shaft,and a distance through which the plated must be turned backwardly beforethe-next new invoice sheet is inserted will he measured or indicated asbefore.

The distance to which the platen must, in any particular instance, heturned backward before inserting an invoice sheet varies according tothe distance necessary to be left on the invoice sheet from the topofthe sheet in the first printed line thereon. and the distancc to-he leftbetween the carbon copies on the record sheet. tcrlnined when changingfrom one style of invoice sheet to another either by experiment or bynoting the line space distance that the platen must he turned backwardbefore a new sheet is inserted in order that the new sheet. when fedforward in position for printing the first line thereon. will have suchrelation to the record sheet that said first line will be at a desirednumber of hue This distance must be de,

space, intervals below the last line of the pre-. ceding carbon copy onsaid record sheet.

The operator having ascertained the number of line space intervalsthrough which the platen must be turned backward for an invoice sheethaving a certain width of heading, places the stop pin K in the desiredhole k, in case the backward movement of the platen is to be arrestedautomatically at the desired point, or if an adjustable stop he 7 5 notused, the operator turns the platen backward until the edge of the arm Jreaches the mark on the scale corresponding with the predeterminednumber of line spaces through which the platen is to be turned backward.He then inserts the new invoice sheet and turns the platen forward untilsuch invoice sheet is brought into position for printing the first linethereon.

.While the pear wheel K is shown as having gear teet 1 extending aroundthe entire circumference, yet the said wheel, in fact, is not adaptedfo'r making a complete revolution so that it in effect constitutes agear segment or curved rack member which may be of any desired lengthaccording to the maximum distance through which it may be desired toturn the platen b ckward.

The pinion I is shown as mounted on the platen shaft, but the sameresult will be produced if thesaid pinion be mounted on another shaftwhich has turning movement to correspond with that of the platen orplaten shaft.

While the rack member heretofore referred to is shown as having the formof a curved rack or gear segment having oscillatory movement about apivotal axis, 'yet it is to be understood that the rack member may he ofother form and otherwise movably mounted so as to have endwisc. movementin such manner that it may be moved backward and forward by the actionof a gear pinion thereon, and my invention includes such a movable rackmember constructed and arranged as shown or otherwise. It is also to beunderstood that my invention, in its. broader aspect, includes a linespace. indicating device which is operated by the turning movements ofthe laten, and which includes means operated by the turning movement ofsaid platen in one direction for throwingth indicating device out ofaction, so as to leave the platen free to turn or rotate in the usualoperation of the machine. and I desire to cover a device embodying thesegeneral features, without limitation to the specificfeatntjegspfconstruction illustrated and hereinbe r dcscribed.
